BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] 1.a. This present invention relates to a Tennis Racket comprisingan elliptical head design supporting a head frame and framing systemangularly 45° mounted and rotated from the tennis racket head long axisor from the dynamic center of gravity with head framing supportingtriple independent strings and strings channels with handle body-framesupporting a mechanical adjustable center of gravity and main framedamper systems.

[0003] 2. Description of the Related Art

[0004] 2.a. Tennis racket have became very popular in the last years forsport and exercises specially in young generation participation, at thesame time and more particularly to improve the general tennis racketperformances with new designs and improved light weight materials likecarbon fiber, titanium and other combinations, improving newconstruction techniques and technologies providing a extra-long tennisrackets with or without integral framing system, strings tensionconfiguration, improvements made over the frame cross sections, allpossible improvements to reduce vibrations and control torsionalelasticity and the most relevant and constantly improvement was madeover the sweet-spot area and all combinations of above mentionedimprovements.

[0005] 2.b. This part of the patent description of the related artrepresents to us a difficult challenge, our present invention related toa tennis racket who supports many mayor changes over the conventionaltennis racket and other relevant technical improvement matters, wechange the shape or in other words we technically re-shaped the headfrom conventional symmetrical oval egg-shaped designs to a originalellipse or elliptical figure whish is geometrically asymmetrical whichis different and advantageous in comparison with the classic tennisrackets design, and after that we rotated in a 45° angle the all framingsystem from is original racket longitudinal axis or head frame longaxis, this particular rotation represent the most advanced improvementin any tennis racket ever build and design, with this head framingsystem angularly rotated 45° we accommodated a 70 cm overall lengthtennis racket measured from the end of the handle and extend the dynamiccenter of gravity or center of percussion up to 54.5 cm measured fromthe end of the racket handle, with this particular measurementarrangement practically and technically its not available in any otherconventional symmetrical tennis rackets.

[0006] 2.c. The other head frame and framing system differences betweenrelated arts and our present invention, in which is followed by thetriple independent strings, in which the triple independent stringchannel system having an triple independent tension adjustable stringsranges, where each independent strings are located and parallellymounted over the peripheral head frame and framing system, the centralchannel supports the named tensor main sole string, individually mountedin a horizontal and transversal directions from the longitudinal axis ofthe racket and crossing only over the central horizontal and verticalportion of the sweet-spot area and the center of the diagonal strings,the other two channels, supporting the second and third series ofstrings, diagonally aligned and parallelly crossing the horizontal andvertical main tensor string over the central sweet-spot area, thehorizontal and vertical tensor main sole string opening 390 cm² ofprimary concentrate triangular string configurations sweet-spot area,and simultaneously control the strings transmission of waves vibrationsrelated to the head frame and framing system, energy transmitted to theball, and control the expansion of the strings automatically, with thisabove particular features it's not available in any other conventionaltennis racket.

[0007] 2.d. The neck section or throat, the difference between relatedarts and our present invention, in which our tennis racket supports aangular head frame and framing system configuration, this neck or throatsection parts and components, technically represents the most relevantinnovations of this tennis racket, and the basic element who makes itpossible to extend the overall length of the racket to 70 cm and locatethe dynamic center of gravity in 54.5 cm measured from the end of thehandle, at the same time, supporting or holding those primary doubleasymmetrically arms or shaft designed in a angular position respect tothe longitudinal axis of the racket, in which this primary arms or shaftextensions supporting through the throat section portion a doublesecondary symmetrically straight extension arms or shaft, this primaryarms or shafts interconnecting with the bottom head long axis and thehead right side short axis cross-section portions of the head frame andframing system of the racket, at the same time, the left primary arm orshaft portion interacts directly with the central bottom long axis headmain frame and framing system, supporting the racket long axis headframe and framing system in 45° angle position, and supports at the sametime the head framing long axis string systems in a angularly mountedconfiguration, at the same time, the right side primary arm or shaftportion interacts directly with the central right side short axis headmain frame and framing system, supporting the racket right side headframe and framing system in 45° angle position, and supporting the headframing short axis strings system in a angularly mounted configuration,the secondary straight arms or shaft forms the single main throat-baseshaft lower central portion of the tennis racket neck section, andinteracts with the handle body-frame and damper systems, with this aboveparticular advanced features are not available by any other tennisrackets.

[0008] 2.e. The handle section differences from the prior related artsand our present invention handle section systems, wherein the topportion of the handle support the throat-base shaft embedded inside thetop portion of the handle body-frame, in which the main function is todamping or absorbing the framing system transmission of waves vibrationsto the hand of the player, the end of the tennis racket handlebody-frame support the fixation of the entirety tennis racketthroat-base shaft system and support the mechanical adjustable knobwhich control the variable extension center of gravity of the tennisracket between 35 to 42 cm measured from the handle end, with thisadvanced future configurations not supported by any other tennisrackets.

[0009] Our principal interest is to present this invention to the tennisworld players and all type of tennis products consumers a totally andrevolutionary new concept state-of-the-art tennis racket,
